CHICOPEE — Carlos Laguer, whose two-hour shootout with police wounded a state trooper and terrorized downtown last Friday morning, had a long record of violent crime in Massachusetts.

Preliminary autopsy reports show the 41-year-old Laguer likely shot and killed himself while holed up in the first-floor apartment at 102 West St.

Trooper John Vasquez, taken to Baystate Medical Center in Springfield for treatment of gunshot wounds to his hand and lower left leg, is now recuperating at home.

Investigators continue to probe Laguer’s violent attack that shaken witnesses described as something akin to the infamous gunfight at the OK Corral or something straight out of a Hollywood movie.

Hampden District Attorney Mark G. Mastroianni said Laguer was armed with more than one weapon – including an “automatic-type weapon.” Investigators believe between 70 and 100 bullets were fired when Laguer and local and state police exchanged gunfire.

It started, Mastroianni said, as a reported domestic disturbance at about 7:45 a.m.

Laguer’s first known brush with the law as an adult in Massachusetts involved a domestic altercation as well.

According to Laguer’s conviction summary, provided by the state Department of Criminal Justice Information Services, he was convicted of domestic assault and battery in Northampton District court in 1994, when he was 24 years old. That summary lists his formal name as Carlos A. Gonzalez Laguer or Carlos Gonzalez-Laguer.

A clear pattern of domestic violence, break-ins, possession and discharge of illegal firearms and assaults on police officers and others ensues, according to the criminal offender records.

In a way, Laguer’s final burst of violence last Friday encapsulates all the elements of his long criminal history.

A year after that first Northampton conviction, Laguer was again convicted, in that same courtroom – this time of violating a restraining order.

More convictions ensued over the years, including two counts of possession of a firearm without an FID card in Holyoke District Court in 1997, assault and battery with a dangerous weapon and two counts of violating a restraining in Northampton in 1998.

Laguer’s most recent convictions – for one of his more violent acts – were handed down in Springfield District Court in 2004. The incident that led to those convictions is eerily similar to last Friday’s – minus the withering gunfire. It was a break-in, followed by an attack on those inside and on the responding police officers.

It started when Laguer broke into an apartment at 20 Healey St. in Springfield on May 21 of that year and assaulted his ex-girlfriend and a man inside.

The victims, according to a report written by Officer John D. Wilson, were able to push Laguer out the door, but not before he inflicted a two-inch scratch on the woman’s chest.

A few moments later, all the windows in the front of the home were smashed out.

When the man went outside to see what was going on, Laguer attacked him. As they rolled around on the broken glass, Laguer bit the man on the arms some 15 to 20 times, according to the report.

When Wilson arrived at the home, Laguer, told that he was about to be arrested for breaking and entering, pushed the officer. Wilson followed with a glancing baton blow to the suspect’s legs, the report states.

The officer then lost control of the baton due to his sweaty hands and Laguer grabbed him by the throat. The man then came to Wilson’s aid and they managed to subdue Laguer.

Once in the cruiser, Laguer went wild in an attempt to get out and struck another officer in the head and chest, according to Wilson’s report.

Laguer was ordered held without right to bail at his arraignment on that case.

In the court file, noted as reasons for the decision to hold him without right to bail are that Laguer had 11 prior convictions for crimes of violence including “numerous abuse prevention incidents” and possessing and discharging a firearm.

Laguer’s record shows numerous jail sentences served for those convictions.

Information in that file shows that by 2004, three women had taken out restraining orders against him for short periods of time, but one of them had taken out restraining orders a number of different times against him.

Laguer was ultimately convicted in the Springfield case of malicious destruction of property, two counts of assault and battery, two counts of assault and battery on a police officer and breaking and entering in the nighttime with intent to commit a felony. He was sentenced to a year in jail.
